Monitor screen problem

I have a Power PC 5600 Mac. My friend gave it to me and she had it since 1994. Recently, it's been acting strange. Every time I boot up the computer it makes a "DZZZT"/grinding sound just before the desktop is to display and then does not display the desktop. I am left with the blue background space only with the gray, empty toolbar on top. Did I contract a virus or is my little old Mac dying? What can I do to fix it?

Hi S.M.
Welcome to discussions.
There is no PPC 5600 neither on everymac nor on apple.specs.
1)Virus-seems to be relatively unpossible.Last I notified was some years ago
2) Did you check the PRAM- battery? You may look at:

For further info(change battery,take apart) you may look at
whoopis.com-with the PPC ????.
Good luck

  • MONITOR SCREEN PROBLEMS - has anyone else had this ? HELP ..

    Friends,
    I am going nuts ( no don't answer that one ! ).
    Recently ( possibly after the 10.5.2 graphics update - I can't exactly recall ) my LG flat screen monitor has started to look like a grainy 60's acid art house experiment !!
    It is subtle but most disconcerting as I use my beloved G5 every day with Logic P8.
    I have tried changing settings - calibration the lot... but still it looks strangely weird - like a TV that is not quite tuned in.
    Gradients and shaded areas have weird lines instead of fine tones and artifacts appear around type and lines where was once beautiful and clear graphics.
    When I first bought the LG 204WT 20" monitor 5 months ago it was fine !.
    I have been using the recommended DVI output and tried different cables and the alternative input - the effect is still there but not quite as bad when using connector to RGB input.
    The shaded areas in finder and Logic are almost transparent and grainy with a light blue / pink halo like effect around windows and graphic boxes.
    I *don't know how to explain it really but I do hope someone out there may have some answers or at least have an inkling of what I'm trying to describe..*
    As if I couldn't make matters worse I did an archive and install to roll back to 10.5.1 early hours of this morning - this didn;'t cure the problem and I lost the use of some music plug -ins and authorizations in the bargain.. Maybe it is time to call it a day and take a long break.
    Really I should get a pen and paper and sit with my guitar an a darkened room for a few days.
    I called the Mac shop where it was purchased then LG but with no help, advice or offers to replace it.
    I guess the monitor basically works but this strange behaviour is arguably quite subtle and may not be considered 'serious' by most people !
    *In the meantime if any of you lovely people could take my situation seriously and offer any practical advise I would be most appreciative.*
    Many thanks - not quite lost it yet - Paul

    Hi Pancenter,
    Many thanks for taking time to message.
    The resoloution is set as it should be and millions of colours is selected etc.
    The screen has had several contrast / brightness adjustments and a factory reset with no improvement.
    Also someone suggested the screen zoom might be on but this is all set as normal.
    I have an imac which works fine and the difference is quite noticable - on the G5 w/ LG screen there are light blue and pink 'halo's ' around gray areas, graphics have strange patchy dots like a screen print and as I am looking and typing into this forum the gradient shaded area that says 'Apple Discussions' has very poor quality shading with horizontal blue lines !
    I've also tested the cables and made sure there are no interferences - this is really weird...
    I will try another monitor when I get chance - thanks again.
    Paul

  • Nokia 5800 express music monitor "screen" problem

    hi all,
    i've a nokia 5800 device and i've faced a very serious problem:
    when i lock the phone and unlock it the monitor or screen dont appear as previous normally, instead of that shaked colored lines appear, so i can't see who is calling. But the touch is working normally so i can play music or answer calls but without knowing who is calling.
    if i switch the phone off then switch it on i see the the screen normally, and when it locked then unlocked the same problem appears again.
    i've tried to solve the problem by formatting the device but it is no use
    the same problem faced my frien
    i don't know what to do, please give me a hand......
    Solved!
    Go to Solution.

    I've been having a very similar problem with my nokia 5800 expressmusic.
    it started off like yours but then the screen went fully black.
    the green, white and red buttons at the bottom work so does the small touch button at the top right.. those lights always come on when i unlock the phone so they're fine.
    I know that my phone is still working because i was randomly touching the screen when the phone was unlocked (even though i cannot see anything on it) and i ended up calling somebody. my only problem is that i cannot see the screen at all!!
    i've tired turning my phone off, taking out sim and memory cards, putting different sims in and charging it.
    nothing works!!
    is there anything i can do?
    can anybody help me with this?
    or is my phone just past its 'use by' date?
    please, please help me!
    thanks

  • Monitor screen problems

    Help help help.....for no particular reason both my screen and open windows have become unattached. They are loose and also the screen size is so enlarged that my desktops icons cannot be seen all at once.  I am actually seasick chasing my loose windows around.  I do not have a cordless mouse.  I have tried two different mice and this same bizarre problem persists.  I am not computer savvy so if anyone responds please make the help dialogue in a very simplistic way.  Thank you

    Oh,  you are the smartest kid in the class. Thank you , thank you...  You solved my problem in the wink of an eye.  There is one problem still remaining which is that all the icons on my desktop screen look too small.  I need
    get it back to its normal size. Also this not not the first time my screen went all looney.  What am I doing that causes this?  I have to leave right now so I won't be able to get back to you immediately.  Also I want you to get all the points possible but I am finding even that challenging...

    When I have video clips on my timeline, they do not play in the monitor screen. I hear the sound track but can not see the image. To test if my new files are somehow the problem, I went back and used video files that I used successfully a year ago, and they no longer play in the monitor window. I hear the sound track, but do not see any video. Have I changed some setting that controls video playback in the monitor window?

    Thanks for the follow up.
    Missing in this equation were the version of Premiere Elements that you were using and the computer operating system on which it was running. But...
    The deed is done. But.....Until now and after you went ahead and moved to version 12, we now learn what version of Premiere Elements you were using. We still do not know the computer operating system involved.
    You just said Premiere Elements 10. Premiere Elements 10 is hit by a serious known display issue if the computer uses a NVIDIA GeForce video card/graphics card. In this issue, the only remedy is to roll back the driver version to about May 2013. The description of the problem and how to do the roll back are described in one of the Announcements at the top of this forum. What video card/graphics card does your computer use?
    On another front, Adobe will be releasing a new version of Premiere Elements any day now. No one but Adobe knows the feature set for the new version. That type of information is announced at the moment of release of the new version.
    So the remedy to the problem that you presented in this thread could have been...
    1. Rolling back the NVIDIA GeForce driver version to about May 2013 if possible (Windows 8 or 8.1 64 bit, may not be possible)
    2. Move to another version of Premiere Elements (which you did)
    I offer the above for consideration so that you can review your decisions. We are pleased to learn that Premiere Elements 12/12.1 works for you.
    Please do not hesitate to ask questions and ask for clarifications, but remember that the answers are in the details.
    Best wishes,

  • I still have the problem with my Power Mac G3 Blue/white.  Turning the power on i can hear it go thru POST but nothing every shows up on the monitor screen.  Also when booting pressing the "C"  or the Shift key nothing happens.

    I don't get anything on the monitor screen.  During startup i can hear it going thru POST but never any screen image.  Any ideas?

    The "C" key will work if there is a bootable volume on a disk in the optical drive. Are you running OSX? Jaguar, Panther, Tiger? On OSX (UNIX) you can use the command "S"  (⌘-S) at start up to go to the root and do a file system check: Type; fsck -f -y  at the prompt when it appears then press Return; let the root check for problems and repair. To exit after the test type; reboot and press Return

  • How to How to install ATI Radeon HD2600 driver on bootcamp 3.0 windows 7 partition w/black screen problem

    Ok....so i've posted this question in a different way, and i gotten several "scratch the surface" answers from people just saying to install "Ati catalyst", or insert the os x dvd and run set up.exe, and update  to boot camp 3.1 or 3.2...while these all seem like great suggestions, I am finding myself needing more specific direction or "hand holding" so to speak.....here is the MAIN problem...
    The Background/history
    I used boot camp (3.0, and i found updates for 3.1 for imac and for windows, but can't find for mac pro, AND they all are ".exe" files which run on windows..which as you'll see is the big part of my problem...So I recently updated my mac pro (with the ATI Radeon HD2600 graphic PCIe card with 10.6.7 from 10.5.8.  I created a single partitioned drive to install windows 7 professional 64 bit.  The download software function didn't work (Thanks, APPLE for that poor level of support) so have to select the option that i have already downloaded, or have other media with the drivers already on it....i restarted with the windows 7 disk in.... 
    The installation of Windows 7 Pro 64-bit
    So the installation of windows 7 seemed to go flawlessly, was able to use my existing 23" hd apple cinema display (so somehow it has drivers that work with the graphics card, or maybe the motherboard's on board video components) and i select english, and install now, custom, blah, blah, blah...installation causes a few reboots, then restarts ultimately back in os x since that is the default boot os i use on this desk top and have to do the "opt" button to select booting in windows....so when i try restarting in windows, now using the actual boot drive on which i am installing it, it ran through another reboot or two, but then after that, my display goes black....  in the communities, the solution sounds super simple... "go download the ATI catalyst for the black screen problem....windows 7 doesn't have device drivers that work with the ATI radeon hd2600...no problem, just go download and install...."
    The problem, re-emphasized :  I cannot even finish the install for windows, because of this driver problem....i cannot see anything....I have tried to reboot in safe mode, and that then seems to invoke whatever basic drivers that do work, likely through the motherboards onboard video vs the actual graphic card, and the screen works and says that it's wanting to complete the installation, so i'm thinking awesome this is gonna work....and then.. "windows installation was not completed and cannot be completed in SAFE MODE, need to restart, blah, blah, blah" pops up...and forces reboot...so Safe Mode allows me to see, but won't allow me to finish the install of windows 7...and without completing the install i can't run (ranther I DONT KNOW HOW TO) any of the various .exe files everyone is telling me are the solutions to my problem...like update 3.1 and 3.2 bootcamp...they're all .exe files?  not sure why, because bootcamp runs in 10.6.7 i thought, but whatever...it needs running Windows to execute...then the ATI radeon hd2600 driver for windows 7 that i downloaded from the site has an installation program that is an .exe file, which needs windows to run...  Does this make sense, why i can't just use these fixes, that seem to be the only fixes out there....so can someone school me step by step here (not just the highlights) of how to update bootcamp, and how to install the ati radeon driver  without having been able to complete the windows 7 installation because the monitor goes and stays black????
    This is so very frustrating for the record...and any substantial help "not just go download this..." would be immensely appreciated.
    Some other things i've been told to try that i've tried and nothing seems to happen as i'm told it will....
    ---I've been told to install the osx dvd and run "setup.exe"  - AGAIN...it's an exe file...and 2 - when i put in the os x file it just wants to re install 10.6...so need more help if this is even a real solution to understand how to make it work...
    ---I've been told to update boot camp to 3.1 and/or 3.2 from 3.0, using Apple Software Update....Well, my software update is saying everything is up to date and there is nothing new to download at all, and when i reverify the bootcamp version it is still only 3.0.2...and again downloading the updates from www.apple.com/support/  for 3.1 and 3.2...all of those are .exe files...need windows to run them...again, refer to the problem described in detail above...
    ---I've been referred to the black screen on imac early 2011 thread saying it should fix my problem...and reading it it SEEMED like the most promising resolution...it involves creating a boot flash drive for windows 7 and an xml file that sets the imac drivers to auto install during the windows installation..and it got me farther than anything else..but still ultimately ended up in the darned black screen...my assumption is that it's because it's for imac and not mac pro so not ati-radeon specific drivers....ok....that's enough..please...anyone who thinks they can help...your help is desperately needed...thanks so much in advance!

    hey Hatter, thanks so much for getting back...so just to be super clear...is there no way to install the drivers using an exe file given my current state? no way to do it with command prompt or something?  if can make work with existing card, i'd prefer it...now when you say it's 'toast' how do you mean?  it works well with the os x partitions and always has...so i'm not sure i follow, just want to be clear...
    Now to your point of starting with only the one drive installed...so i would put that bootcamp drive in bay 1 and disconnect the rest...i'm not totally sure what you're suggesting the effect should be of doing this?  just that i'm just installing windows without the bootcamp deal...but if windows 7 doesn't support the ati radeon hd2600, it still will go black screen no? or you're saying it will run video through the motherboard if it's the only bootdrive, and will run all the way through the windows install without trying to switch over to the hd2600?  (slrry flr these questions..just really want to make sure i understand what you're telling me..thanks so much for your patience and help by the way...it's very greatly appreciated...your support is priceless!
    So now, assuming none of the above is possible...referring now to the ati 5770 that you referred to...you mention it works with 10.6 well, and that windows 7 supports it ...2 questions on that
         1) Windows 7 supports" meaning, out of the box windows 7 supports it? or will i have to install drivers still through some update, because again, if that's how i have to do it, then won't work, cuz can't start windows to see anything to install any drivers or run any thing at all...so it would have to just work with initial installation.
         2)hardware wise for my Mac Pro 3,1...intel dual quad core xeon, blah blah....will this card work? it's a PCIe and should fit on my board no prob, etc?

  • I have very thin, colored lines running vertical on my desktop monitor screen.  I don't know where they come from or how to get rid of them.  I started with one and now have three.  Can anyone give me some insight about what to do in getting rid of them?

    I have very thin, colored lines that have shown up on my IMac monitor screen.  I don't know where they came from or how to get rid of them.  I'm concerned now because I started with one and now have three.  Does any know why this occurs or how to get rid of them?

    I got an address from Applecare, although I can't place my hand on it right now. I didn't bother persuing the letter route myself as I didn't expect much. I know that the location was Cork, Ireland though as that where the UK Applecare is based as far as I'm aware. The best thing to do is to call Applecare (if it's free) and discuss the issue. State that you are not happy wit the fact that you will have to pay to have the problem resolved especiiay if it is an ongoing problem that has not been resolved. I ended up speaking to a senior manager of the Applecare team who then proceeded to tell me about mailing in my grievence to customer services division or something like that.
    If I can find the address I may post it if I'm allowed.
    In the case of age, Schools usually have a 5-year life-cycle as they tend to be used differently than consumer machines, i.e. being used constantly on a daily basis for at least 12 hours with no break. you would expect issues to appear after a few years, but I expect problems that arise through defects to be resolved and stay resolved. As I mentioned we had machines for around 2 years before the lines appeared and sent them to be repaired. I'm happy with that. What I am unhappy about is the fact that the problem has reappeared exactly in the same way and now I'm left with around 7 machines that I either pay loads to repair or, the more likely replace the machines with newer ones since the age is now big enough to warrant the replacement.
    Sorry for the lengthy moan, but these are the reasons I purchased Apple ahrdware in the first place to avoid the "not our problem" stance some PC vendors  usually take, similar to the Dell monitors thread mentioned in here somewhere.

  • My monitor screen scrolls up and down on its own by it's self? How do I stop it?

    How do I fix a monitor screen scrolling up and down on its own?

    Sabrasam,
    Thank you for your quick reply.
    I want you to try a factory reset on the monitor if you haven’t attempted one already.
    1.       Press the Menu down in the bottom right corner of the monitor.
    2.       Once the on screen display appears toggle down to factory reset.
    3.       Select on that option
    You might see your monitor go dark a couple times but that is normal. Test it out after the reset.
    If I have been helpful or if you'd like to say thank you for me trying to help, click the white star under my name to give me Kudos. I really appreciate it.
    Please respond at your earliest convenience.
    Thanks
    Clicking the White Kudos star on the left is a way to say Thanks!

  • Wierd monitor compatibility problem

    Hi all,
    Got a wierd monitor compatibility problem. G3 works fine on a sony 21" CRT.
    Connected it to a Daytec 15" CRT which works fine with a windows 98 PC.
    With the G3 I get the apple and the spinning up logo then the screen just goes blank.
    Is this monitor PC only or something? It is an old monitor but I thought any monitor should work
    if the vga connector fits?

    So you are using this directly plugged into the stock Display card in a Blue & White G3 with NO adapter?
    The Mac is probably still set for a higher resolution that the SONY can do, and has not noticed the display has changed.
    Video pros says that Video can be plugged and unplugged all day long with no bad effects. If your old display is still around, try setting it to 640 by 480, save changes, and swap the other one in "live" at that resolution.
    Other tricks:
    Reset the PRAM. This will send you back to a default setting while booting up, but may change when the system becomes active.
    Boot from a CD. This ignores the settings on your Hard drive, and boots to a very simple resolution like 640 by 480 to ensure that Most Macs can start up with it.

  • I have an Imac.  When I click to open google maps a permeable but dark screen covers my monitor screen and I get a note that tells me to shut down the computer and restart it.  This hasn't helped.  Everything else seems to work fine.

    When I attempt to open google maps in Firefox on my Imac, a dark screens descends over my monitor screen and a note tells me there's been an error, no number is noted, and that I need to turn off and restart my computer.  This doesn't help, but everything else works, including google maps in other browsers.

    This is a kernel panic.
    First verify that Firefox is fully updated including all extensions.
    If this fails to fix....
    Restart in Safe Boot mode then open Firefox.
    *  shutdown
    *  start the Mac and *wait* for the startup chime to sound
    *  after the sound, press and hold down the shift key
    *  keep holding and *wait* until the grey  Apple logo appears
    *  now release the shift key and just wait (it could take a few minutes)
    *  eventually the login screen appears with the words SAFE BOOT
    *  login and open Firefox.

  • Qosmio F10: Monitor screen looks like an Andy Warhol picture

    I am currently having problems with my monitor screen looking like an Andy Warhol picture. I have resorted to going through the Product Recovery DVD-ROM for my Qosmio F10/G10 Laptop in the hope that reverting it back to the factory settings would solve the problem but it hasn't.
    The screen breaks down after the Windows welcome screen, leaving me with my desktop all Andy Warhol like (i.e. blocks of pixilated colour at the edges of the graphics). I have tried to reset the resolution which solves the problem to an almost acceptable level but on a temporary basis, because the problem re-appears again when I re-boot the laptop.
    I think that it is something to do with the Windows Multimedia Operating system that was preinstalled on my computer (so no recovery disc). The reasoning behind this assumption is that I put a DVD film into the Multimedia that is part of Windows XP and the film is a moving Andy Warhol video.
    I put the same DVD into the WinDVD that came as a Toshiba additional content and the DVD is perfect! My reasoning is, that if there was something wrong with the hardware of the Laptop, then all DVD reading programs would react the same way, but as they do not, it must be a programming (or operating system problem).
    Am I on the right lines? Is there a way to solve the problem via a downloadable file?

    Thanks guys for your replies, sorry if my question is confusing, but I couldn't think of any other way of describing it without the use of a screen dump to show you.
    At the moment I haven't got another monitor to try, even though this looks as though it would have been the easiest option. I shall start asking round to see if I can borrow one to eliminate that variable.
    However I will try to reinstall and to update "Graphic Drivers" to get rid out of this display problem.
    Thanks to all.
